Used in immunological research to detect and quantify sheep interferon gamma (IFN-γ) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is particularly applied in studies related to infectious diseases in sheep, including tuberculosis, paratuberculosis, and other intracellular pathogens where IFN-γ serves as a key marker of cell-mediated immunity. It supports vaccine development and evaluation by measuring immune responses. The kit is also used in veterinary diagnostics and research to monitor disease exposure and assess the efficacy of immunotherapies. Its high sensitivity and specificity make it suitable for both experimental and field studies in animal health.
